Allows virtually no current to be conducted through it. With an ultra-high internal impedance of 100 giga ohms (100 x 109 ohms), the Nordson kV meter conducts no more than 1 micro-amp of current at 100 kV, making it possible to measure power supply output in virtually open-circuit conditions for maximum accuracy.

100 giga ohm internal resistance conducts no more than 1 µA of current at 100 kV to provide maximum accuracy
